Effect of replacement of soybean meal protein by nigella sativa meal protein on performance of growing Japanese quial [electronic resouce].

Includes references.

An experiment was conducted with Japanese quail to investigate the effect of replacement part of soybean meal protein (SBMP) by different levels of Nigella sativa meal protein (NSMP) (4.0. 8.0, 16.0 and 32.0",4,) on the growth performance. some blood plasma parameters, chemical carcass compasition and carcass characteristics. A total number of 300 unsexed Japanese quail chicks at 7 days of age were randomly distributed into five experimental groups each in three replicates containing 20 birds each. The treatments were control group (0.0 NSMP). 4.0. 8.0, 16.0 and 32.0%, NSMP. Birds were placed in electrically heated battery till the end of growing experimental period Diets were formulated to be isocaloric and isonitrogenous provide 24.0 % CP and 2900.0 ME Kcal/Kg of the diet. Both diet and water were given ad libitum. Lighting program was adjusted to met 24 hours of light daily. The experiment lasted 5weeks from the start. The obtained results indicated that the highest values of body weight, body weight gain. fred consumption andprotein intake were observed for groups fed 4.0 or 8.0 % NSMP at the end of experiment. followed by groups fed 16.0, 32.0% and control group. While. insignificant differences were observed among dietary experimental groups for fred conversion ratio. Substitution soybean meal protein by different levels of NSMP protein caused decreases (P ≤ 0.05) of protein efficiency ratio as compared with control group. Insignificant differences were detected for mortality rate. Carcass chemical compositions were not significantly affected due to feeding different levels of NSMP. with except of ash percentage where. it decreased by the increases NSMP % in the diet.
